Shaping 3D Path of Electromagnetic Waves Using Gradient‐Refractive‐Index Metamaterials
نویسندگان
چکیده
An all-dielectric semispherical lens with functions in shaping 3D wave-propagation paths is proposed and experimentally verified. When radiation sources are placed in the central region, the lens behaves as a magnifying device to resolve the sources in subwavelength scale; while when the electromagnetic waves impinge on the semispherical lens from outside, they will be guided spirally inward.

Microstrip Antenna Gain Enhancement using Near Zero Refractive Index Metamaterials
Some useful features of microstrip patch antennas are low profile, low weight and easy fabrication. However this type of antenna suffers from having a low gain, caused by propagation surface waves. In this paper, a new near zero refractive index metamaterial (MTM) unit cell is designed and fabricated as a superstrate over a Rectangular Microstrip Patch Antennas (RMPA). In order to obtain a maxi...
متن کامل3D isotropic metamaterial design using smart transformation optics
We introduce new design method for 3D isotropic transformation optics device using smart transformation optics. In 2 dimension smart transformation optics, elastic deformation satisfied quasi-conformal transformation with negative Poisson’s ratio -1. We extended smart transformation optics to 3 dimension and demonstrated 3D isotropic metamaterials waveguide. This 3D waveguide is arbitrary benda...
متن کاملElectromagnetic wave propagation in gradient index metamaterials, plasmonic systems and optical fiber networks
Metamaterials constitute a relatively new field which is very promising because it exhibits properties that may not be readily found in nature. One of promising lines of research is the study of novel characteristics of the propagation of electromagnetic (EM) waves in gradient refractive index (GRIN) lenses. In this Thesis, three geometrical optics methods as well as a wave numerical method hav...
متن کاملTopology and Design of Wide-Band 3D Metamaterials made of Periodically Loaded Transmission Line Arrays
We propose a new topology for realizing artificial microwave materials that exhibit a negative refractive index over a wide frequency band. These metamaterials consist of a threedimensional transmission line mesh that is loaded with reactive series and shunt elements to create negative permittivity and permeability. The cubic-cell transmission line host network is a physical realization of the ...
